Can't use BLE_NUS_C_EVT_DISCONNECTED on multilink

[Nicolas Brunner]

The BLE_NUS_C_EVT_DISCONNECTED of the ble_nus_c_evt_handler() give a conn_handle = BLE_CONN_HANDLE_INVALID. So it's not possible to know which peripheral got disconnected when multiple connections are allowed.

Why BLE_NUS_C_EVT_DISCONNECTED doesn't give which peripheral got disconnected ?
